ᐅ Upper floor lintel and ring beam

Hello,

we are planning a clear structural height of 2.75m (9 feet) for the upper floor. Our builder mentioned that with this height, the windows might not be very tall (he hasn’t given exact details yet), since the window lintel and ring beam (for the town villa) still need to be taken into account. Do you know how much space is needed from the top edge of the window to the ceiling? We want to calculate ourselves whether the structural height will be sufficient.

Best regards
Sabine

In our case, the ceiling rests on the ring beam. If the ceiling joists are at the height of the ring beam, then the ring beam cannot be continuous all around. Or am I missing something?

Could you please upload a picture of it?

Hello,

It’s not very clear to see, and my earlier statement wasn’t entirely accurate, as I realized this afternoon. The ring beam is cast about 10cm (4 inches) lower than the ceiling joists and simultaneously serves as the lintel.

What can be seen: The ring beam on the exterior walls is higher than on the interior walls. At the back, the central purlin rests on the outer ring beam. In the middle, the ceiling joists rest on the inner beam. The outer one is as much higher as the height of the ceiling joists.

Unfortunately, I don’t have a better photo at hand right now.
